Question

torque on a sliding ladder.

Answer 1

ok so the problem is asking me to find the minimum coefficient of static friction and i did and got \[\mu_{s}=\frac{1}{\tan\theta \left( \frac{ m_1+m_2 }{ m_1\frac{ d }{ L }+\frac{ 1 }{ 2 }m_2 } \right)}\]and now it's asking me to find magnitude of the force of the friction applied by the floor to the ladder. it also says that \[\mu_s=\frac{ 3 }{ 2 } \mu_\min\]i just plugged it in and got\[\mu_\min=\frac{ 2 }{ 3\tan \theta \left( \frac{ m_1+m_2 }{ m_1\frac{ d }{ L }+\frac{ 1 }{ 2 }m_2 } \right) }\]now i'm just stumped on what to do next.
